Cancer is one of the most dreaded disease of human beings and is a major cause of death all over the globe
. More than a million Indians suffer from cancer and a large number of them die from it annually. The mechanism that underlie development of cancer or onogenic transformation of cells its treatment and control have been some of the most intense area of research in biology and medicine. In our body cell growth and differentiation is highly controlled and regulated. In cancer cells there is a breakdown of these regulatory mechanisms. Normal cells shows a property called contact inhibition by virtue of which contact with other cells inhibits their uncontrolled growth. Cancer cells appears to have lost this property.
